Forget about the above.... Mental note to myself: don't try to fix anything late night after an stressing day ;) The reason for the breakage is right; the diagnosis is wrong. The files at linux/include aren't c/c to v4l/ dir; they're linked with -I. Yet, compiling here are giving several errors: /home/v4l/media_build/v4l/dvb_frontend.c: In function 'dvb_frontend_clear_cache': /home/v4l/media_build/v4l/dvb_frontend.c:952:17: error: 'NO_STREAM_ID_FILTER' undeclared (first use in this function) /home/v4l/media_build/v4l/dvb_frontend.c:952:17: note: each undeclared identifier is reported only once for each function it appears in /home/v4l/media_build/v4l/dvb_frontend.c:969:11: error: 'LNA_AUTO' undeclared (first use in this function) /home/v4l/media_build/v4l/dvb_frontend.c: At top level: /home/v4l/media_build/v4l/dvb_frontend.c:1025:3: error: 'DTV_STREAM_ID' undeclared here (not in a function) /home/v4l/media_build/v4l/dvb_frontend.c:1025:2: error: array index in initializer not of integer type /home/v4l/media_build/v4l/dvb_frontend.c:1025:2: error: (near initialization for 'dtv_cmds') /home/v4l/media_build/v4l/dvb_frontend.c:1026:3: error: 'DTV_DVBT2_PLP_ID_LEGACY' undeclared here (not in a function) /home/v4l/media_build/v4l/dvb_frontend.c:1026:2: error: array index in initializer not of integer type /home/v4l/media_build/v4l/dvb_frontend.c:1026:2: error: (near initialization for 'dtv_cmds') /home/v4l/media_build/v4l/dvb_frontend.c:1027:3: error: 'DTV_LNA' undeclared here (not in a function) /home/v4l/media_build/v4l/dvb_frontend.c:1027:2: error: array index in initializer not of integer type /home/v4l/media_build/v4l/dvb_frontend.c:1027:2: error: (near initialization for 'dtv_cmds') /home/v4l/media_build/v4l/dvb_frontend.c:1060:2: error: array index in initializer not of integer type /home/v4l/media_build/v4l/dvb_frontend.c:1060:2: error: (near initialization for 'dtv_cmds') Very likely becase gcc is using the DVB uapi under /usr/include, instead of the one at the building system. Maybe that's because of the very large number of include dirs added by our building system: gcc -I/home/v4l/media_build/v4l -Wp,-MD,/home/v4l/media_build/v4l/.dw2102.o.d -nostdinc -isystem /usr/lib/gcc/x86_64-redhat-linux/4.7.2/include -I/home/v4l/media_build/v4l/../linux/include -I/usr/src/kernels/3.6.1-1.fc17.x86_64/arch/x86/include -Iarch/x86/include/generated -Iinclude -include /usr/src/kernels/3.6.1-1.fc17.x86_64/include/linux/kconfig.h -I/home/v4l/media_build/v4l/ -I/home/v4l/media_build/v4l/../linux/include -D__KERNEL__ -I/home/v4l/media_build/v4l/ -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Wno-format-security -fno-delete-null-pointer-checks -O2 -m64 -mtune=generic -mno-red-zone -mcmodel=kernel -funit-at-a-time -maccumulate-outgoing-args -fstack-protector -DCONFIG_AS_CFI=1 -DCONFIG_AS_CFI_SIGNAL_FRAME=1 -DCONFIG_AS_CFI_SECTIONS=1 -DCONFIG_AS_FXSAVEQ=1 -DCONFIG_AS_AVX=1 -pipe -Wno-sign-compare -fno-asynchronous-unwind-tables -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -mno-avx -Wfram!
